Split one file into 2 and renaming the file name

For example of one file:

348657856**56985897568976
N1*PR*Jasmine sdgugu
gughyug
35647856834756
REF*2U*7248
gfhgfdugs
ghdugyuigy4576
4867586
N1*PR*John ~
eghufgguigr
4975876346
REF*2U*SMIL
tfgugrt47587
CAS495787656
5687564

Open in new window

I want to spilt N1*PR*Jasmine to be:

348657856**56985897568976
N1*PR*Jasmine sdgugu
gughyug
35647856834756
REF*2U*7248
gfhgfdugs
ghdugyuigy4576
4867586
CAS495787656
5687564

Open in new window

And
N1*PR*John ~

348657856**56985897568976
N1*PR*John ~
eghufgguigr
4975876346
REF*2U*SMIL
tfgugrt47587
CAS495787656
5687564

Open in new window

However, some files just contain one name, I want them to just leave those files alone?

And for each file that had two, I want the filename like for example if the filename was for the one above :

98475789456.5010.4676897.edi
after splitting them, I want it to show as
98475789456.5010.4676897.edi
98475789456.5010.4676897_copy.edi

$files = './';
$dh  = opendir($files);



$i = 5010;
while(! feof($files)) {
	$contents = stream_get_line($dh,1000,"REF*2U*");
	file_put_contents('new_file.'.$i. $contents);
	
}

I have the code above, but it doesn't seem to work with me.

I'll try to help, but I strongly suggest you consider posting this in E-E Gigs. It's not really a question with an answer, so much as a requirement for application program development, and for that you will be much better off to work with a professional developer.

Ray Paseur

This should help you get started. I do not understand the rules for the file names, but you can write each of the EdiFile objects into its own file using any name that makes sense for your application.

This should also work correctly with a file having only one embedded signal.

Okay, thanks but if there is more than one jasmine, can it keep the file as it is, Like if the name is different thats when it'll split?

Also is there a way by using array_splice that I can make the removal of the last two lines dynamically, because some are 5 when some are two (like the example)
